Binding
Surface Plasmon Resonance (SPR) Assay: Binding of inhibitors to expressed cyclophilins was determined using surface plasmon resonance (SPR) experiments. Briefly, avi-tagged cyclophilin proteins with mono-biotinylation were immobilized onto a Biotin CAPture chip (GE Healthcare, cat. #28920234). SPR experiments were carried out on an upgraded Biacore T200 system using a running buffer containing the inhibitor, 10 mM HEPES, pH 7.4, 150 mM NaCl, 0.05% P20, and 3% DMSO. Single-cycle kinetics measurements were used to study the interactions between cyclophilin inhibitors and different cyclophlins. Accordingly, compound at various concentrations was injected to the flow cells with a contact time of 1 min each at a flow rate of 50 μL/min. The final dissociation phase lasts for 10 min following the sample injection. Data was analyzed using Biacore T200 Evaluation Software Version 1.0 and a 1:1 binding model was applied to fit the data to obtain kon, koff, and KD.
